ADJUSTABLE CHIMNEY.

$PECIPICA'IION forming part of Letters Patent No. 334,587, dated January19, 1886.

Application filed September 19, 1885. Serial No. 177,550. (No modeLi Toall whom it may concern:

Be it known that 1, JAMES D. JILLsoN, a citizen of the United States,residing at Willimantic, in the county of Vindham and State ofConnecticut, haveinvented certain new and useful Improvements inAdjustable Chimneys, which improvements are fully set forth anddescribed in the following specification, reference being had to theaccompanying drawings, in which Figure 1 is an elevation of a chimneyprovided with my newly-invented top. Fig. 2 is a vertical section ofsaid chimney, and Fig. 3 is a detached top view of the section whichforms the cap of the chimney. Fig. 4 shows said cap as applied to achimney formed, in the usual manner, of brick.

My invention relates to certain improvements in that class ofchimney-tops made of iron or other similar material which may be readilyformed or molded to the desired shape; and my immediate object is toproduce a chimney-top which may be adjusted to fit chimneys of differentsizes and to protect the brick-work from undue dampness, as hereinafterreferred to.

I am aware that there have been made heretofore metallic chimney-capswhich could be adjusted to fit chimneys of various sizes; but, so farasI am acquainted with the state of the art, such caps have beendefective in that their construction allowed rains and snows to enterand remain between said metallic caps and the brick chimney, and theconstant dampness thus generated soon acts to destroy the life of themortar. I have not only improved said caps to overcome said defect,buthave also produced a complete adj ustablechimney-top which, beingattached to the brick chimney below the roof, or at the point where saidchimney passes through the roof, protects the chimney from the action ofthe weather.

Referring to the annexed drawings, the letter a represents the chimneyproper, formed of brick, in the usual manner, and the letters I) brepresent the pitch of the roof. Just below the point where the chimneyis to pass through the roof a cast-metal cap, 0, is slipped over thechimney a. This cape maybe of a single piece, or may be formed of aseries of sections,

substantially like the portion which extends above the roof, and which Iwill proceed to describe. The sections d, e, and f are each formed offour or more rectangular pieces, one arm of each piece having anextension, '5, of the same shape in cross-section as the main piecewhich it forms a part of, but enough smaller, so that it may easily slipinto the piece next adjoining, as will be understood by referring to thetop view of cap f in Fig. 3. The several sections of each series aresecurely fastened together by bolts or screws h, a slot being providedin one section, so that the de sired adjustment may be made without en:tirely removing said bolts or screws. After the proper adjustment hasbeen once attained the bolts or screws are turned home, and the severalsections become practically a single solid piece.

In Figs. land 2 I have shown the chimneytop as formed of four sections,0, d, e, and f; but the number may be varied, according to the style orsize, and the adjoining ends may be beveled, as at 70, or may betelescoped, as at m, to form a strong, but easily-made, joint. In casesWhere the adjustment thus provided is not sufficient, I introducebetween the angleiron pieces 0, one of whose ends receives the extension1', its other end being provided with a similar extension, which entersthe opposite angle-iron. (See Fig. 3.) These extensionpieces 0 areapplicable not only to the capsection, but also to any or all of thesections which form the complete chimney-top.

In Fig. 1 I have shown in dotted lines the pitch of the roof as locateda considerable distance below the full lines I) 12, before described. Insuch a case the section 0 should be carried downward, as also indicatedin dotted lines.

The last-described construction improves materially the outwardappearance of the chimney-top, and also carries the joint betweensections 0 and 01 above the ridge of the roof, where it may be moreeasily reached for repairs. and of the section 0 are inclined toward thecenter of the chimney, for the purpose of turning inward any water thatmay find its Way down the chimney.
